My understanding is a server control's constructor is called by the page's constructor. This happens before Page_PreInit event. A server control's Init event fires after Page_PreInit. It seems a server control does not do much during the Init stage? Then why bother giving much emphasis to Init stage? ...

Hi, I know there is a ListBoxFor extension method among the ASP.NET MVC Html helper extension methods, but I always thought that a checkbox list is more user-friendly than a list box. There was a very convenient CheckBoxList control in good old WebForms, but obviously that is out of the picture now. The question is, why is there no wa...
